    Colocalization of plaque macrophages and calcification in coronary plaques as detected by optical coherence tomography predicts cardiovascular outcome

    Both plaque macrophage infiltration [1] and calcification [2] are recently suggested characteristics of plaque vulnerability in coronary lesions. Each of these two morphologic characteristics may foster the other. [3, 4]. Thus, the aim herein, is to evaluate this interdependence using optical coherence tomography (OCT), which, due to its supreme resolution, has the ability to detect both features. A recent study defined colocalization of macrophages and calcification (ColocCaMa) as a distance < 100 µm between plaque macrophages and calcification. In this work an association was described between ColocCaMa and the more heavily calcified, but also less advanced and more vulnerable coronary lesions ...
